Okay, have been asking around a few sites, even emailed Snipergen. Got nothing out of them. I come here to ask for the model now that I see how nice and efficient this forum is. I also like seeing the maps coming out of the forum. Anyways, copy-paste from other forum:
The base itself is formed out of metal, and has a Snowplow attached to the front due to the snowy environment. The cart carries 3 blue nuclear waste barrels, strapped to the metal bars on the side of the cart. The snowplow also bears a strong resemblance to a Cow-catcher, if that helps.
The Dispenser on the back is almost entirely the same as the one on the original Payload. Except, the dispenser has a belt of Natascha's bullets laid over it.
The main cart is sort of like a scissor lift without the actual "scissor lift". So, like this:
But without the scissor part.
The wheels on the bottom are close together, as seen on the normal Payload:
The whole Payload should be very symmetrical, other than the back, dispenser area.
For the "smokestack" emitter/health dispenser, use the Kritzkrieg for most of the design:
Most notably the glowing parts of the Kritzkrieg.
[/copypaste]
I really hope this can be made. The map I've been working on would really be much better if this was made.
The Map, in Summary:
A Payload map, based in a northern, snowy mountain area where oil pipelines run near. The map begins outdoors, in the beginning of a blizzard. As the two outdoor points are captured, the cart is pushed down into the Mountain, where RED has been stockpiling weapons. The 3rd point is at the end of a mine shaft, where the technologies of RED begin. The 4th point is within a bunker area. The fifth, outside a row of Blast Doors leading to the final point. One blast door is opened after it's respective point has been captured, making the final area (a large arena built atop stalagmites (tites?) in the ground) inaccessible to any team until 5 of the 6 points are captured. In the final point arena, death by clumsy painfulness is very possible and the RED team must use distinct tactics to make sure BLU can't traverse the narrow catwalks leading to the final point.
Thanks to anyone that is willing to do this!
